ScienceWiz(R) Inventions: This multi-award winning book and kit uses everyday materials to build
- A spinning motor
- A clicking telegraph
- A light-flashing generator
- A real radio.
The use of simple materials (no plastic required) helps to demystify the "why" as well as the "how." The step by step, fully-illustrated, 40 page book makes the projects very doable and the explanations easy to understand.
Imagine building a working radio using only aluminum foil, wire and a diode. That's it. No battery required. Now make a spinning motor using only paper clips, a magnet, a bit of wire and a battery. Light a bulb by spinning a coil of wire next to a bar magnet. Make a telegraph click and send coded messages to a friend using just two paper clips, a nail, wire and a battery. Every day materials, indeed!
These are all
inventions with coils. With these inventions you can explore the discoveries of Michael Faraday and Nikola Tesla, two scientists whose work led to the creation of the electrical grid.
